Biography
Guillaume Schweicher is a FNRS Postdoctoral Fellow at the Université Libre de Bruxelles (ULB) in Belgium and a visiting scientist at the University of Cambridge in UK. He received his Master in Chemical Engineering (2008) and Ph.D. (2012) from ULB, followed by post-doctoral appointments at Stanford University (US, 2013, Zhenan Bao) and the University of Cambridge (UK, 2014-2019, Henning Sirringhaus). His current research interests are the fundamental understanding of the physical and chemical phenomena taking place in the fabrication processes, during operation (charge, heat and spin transport) and stability/degradation of electronic devices made of organic semiconductors.
